Abu Dhabi agreed to set up a $6.76 billion storage facility in Johor state in southern Malaysia, state-run 1Malaysia Development Berhad (1MDB) said in a statement.

The facility will be able to store 60 million barrels of crude oil and petroleum and is for Abu Dhabi’s sole use, said the company.

Abu Dhabi’s investment arm will also set up a $5.79 billion investment fund with 1MDB, as well as support a financial district 1MDB is developing in Kuala Lumpur, becoming its “first major multinational anchor investor”, the company said.

Najib, who is facing what are expected to be his coalition’s toughest elections ever against a resurgent opposition, has sought foreign investment as part of his aim for Malaysia to achieve “developed-nation” status by 2020.

But critics of his policies have pointed out that some previous investment plans announced amid fanfare eventually crumbled as foreign investors balked at preferential treatment for government-linked companies.

The foreign ministry said in a statement before the crown prince’s visit that trade and investment between Malaysia and the UAE has seen “tremendous” growth in recent years.

Last year, the UAE was Malaysia’s largest trading partner in the Middle East with total trade amounting to $8.0 billion, up from $6.8 billion in 2011.

Oil-rich Abu Dhabi is the capital of the UAE, a federation of seven emirates.
